摘　　要：阳山金矿带位于扬子板块、松潘-甘孜地槽褶皱系和秦岭地槽褶皱系交接的碧口地体北缘的文县弧形构造带内,矿体赋存于泥盆系中统三河口组浅变质碎屑岩建造中。矿体与围岩界线模糊,研究矿区围岩蚀变特征对下步找矿工作有一定的指导意义。The Yangshan Au ore belt lies in the Wenxian arcuate structural zone on the northern margin of the Bikou terrain which is located at the intersection between the Yangtze plate and the Songpan-Garze fold system and the Qinling fold system. The Au orebodies are confined to epimetamorphic clastic rock of the Middle Devonian Sanhekou Formation. Such wallrock.alteration as silicification, sericitization, chloritization, carbonation and argillic alteration are well developed.
